miRNA-210 expression is associated with iron deficiency and biochemical parameters in hemodialysis patients.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: This study aimed to evaluate the potential of microRNA (miRNA)-210 as a biomarker for distinguishing iron deficiency anemia (IDA) from functional iron deficiency (FID) in hemodialysis (HD) patients. The diagnostic performance of miRNA-210 was also compared with conventional biochemical markers, including hemoglobin (Hb), ferritin, transferrin saturation (TSAT), and zinc protoporphyrin (ZnPP). Methods: Fifty HD patients were classified into control, IDA, and FID groups according to Hb, ferritin, and TSAT criteria. Pre-dialysis blood samples were collected, and plasma miRNA-210 levels were measured using reverse transcription quantitative polymerase chain reaction (RT Results: Plasma miRNA-210 levels were significantly higher in the IDA group compared to both the control ( Conclusion: miRNA-210 may serve as a supportive biomarker, reflecting the interaction between hypoxia and iron metabolism in distinguishing IDA from FID among HD patients. These findings indicate that miRNA-210 could provide additional value in understanding anemia pathophysiology and enhance diagnostic evaluation. Limitations: Key limitations include the small sample size, single-center, cross-sectional design, absence of a healthy control group, and lack of molecular-level functional validation. Larger multicenter studies are needed to confirm these findings and determine clinically relevant cut-off values for miRNA-210.
